Cups to gallons (gal) conversion factors are listed below (for US, UK and for both fluid and dry measurements). To find out how many gallons in cups, multiply by the conversion factor or use the converter if the conversion is from US cups to US fluid gallons.

1 Cup [US] = 0.0625 (1/16) Gallon [Fluid, US]

1 Cup [Metric] = 0.055 Gallon [UK]

There are 1/16 (0.0625) gallons in a cup, because from the smallest to the largest units from cup to gallon, a cup is a half (1/2) pint, a pint is a half (1/2) quart and finally a quart is a quarter (1/4) of a gallon, that makes 1/2 * 1/2 * 1/4 = 1/16 gallons in a cup.

For example, to calculate how many gallons of water or milk there are in 8 cups in US, multiply the cup value by the conversion factor, 8 cups * 1/16 (gal in 1 cup) = 1/2 (or half) gallons of water or milk in 8 cups.
